Calculates the moving average of a time series

Så här använder du det här kommandot...

#### Från menylisten:

Choose Data - Statistics - Moving Average

#### Från gränssnittet med flikar:

Choose Data - Statistics - Moving Average.

On the Data menu of the Data tab, choose Statistics - Moving Average.

### Data

Input Range: The reference of the range of the data to analyze.

Results to: The reference of the top left cell of the range where the results will be displayed.

## Trim input range to actual data content

Check this box to allow trimming of the input range to the actual data content before computing moving-average. Trimming data ignores unused or empty cells after the last non-empty cell in the input range, thus reducing the computing load of the moving average to the actual data. This checkbox is enabled by default.

#### Grouped By

Select whether the input data has columns or rows layout.

## Parameters

Interval: The number of samples used in the moving average calculation.

#### Example

The following table has two time series, one representing an impulse function at time t=0 and the other an impulse function at time t=2.

| A | B
--- | --- | ---
1 | 1 | 0
2 | 0 | 0
3 | 0 | 1
4 | 0 | 0
5 | 0 | 0
